Hang Up

Nana is on the phone and wants to talk to Legend.

Legend lets Daddy put the phone to his ear.
Legend - "Hi Nana! Nanaaaaa! Train. Choo choo. Nana."

Daddy - "Say love you."
Legend - "Love you."
Daddy - "Say see you later."
Legend - "Later."
Daddy - "Say bye bye."
Legend - "Bye bye."
Daddy - "Say love you."

Legend pushes the phone away from his face, looks at it, and presses End perfectly, hanging up the call.

I guess when he says "bye bye", he means it.
